Of his 1960s Radio Luxembourg show called Teen & Twenty Disc Club, Savile told Mr Dann how he encouraged young girls to listen to his show with their radios under their bedclothes.

Savile said: “And my mother, God bless her soul, was more startled when girls used to say ‘Are you Jimmy’s mother? I’m under the bedclothes with him’.”

The Met Police has said it has 340 “active lines of inquiry” and 60 potential victims have come forward.

Crimes under investigation are thought to have taken place over six decades in studios, care homes, schools, hospitals and nightclubs.

TV actress Julie Fernandez, who owns a craft shop in Ellington and claims to have been inappropriately groped by Savile when she appeared on Jim’ll Fix It aged 14, was appalled to learn another victim had been identified.

She said: “That is absolutely dreadful. It is disgusting that he has been preying on vulnerable young girls.

“Although I wasn’t sexually abused, his touching of me was totally inappropriate. Being a predator he was very clever in my case because it was a room full of people.”
